FloatBuffer and 'put( float[] src )'

[maxkiva]

Hi All,
I am trying to use FloatBuffer created on top of ByteBuffer and having problems with using 'put ( float[] src )' method. 'put' for individual values seems to be working fine. Heres is the sample code:

import java.nio.ByteBuffer;
import java.nio.ByteOrder;
import java.nio.FloatBuffer;

public class TestFloatBuffer
{
	private static final int COUNT = 3;
	private static FloatBuffer _fbb = null;
	
	/**
	 * @param args
	 */
	public static void main(String[] args)
	{
		ByteBuffer tbb = ByteBuffer.allocateDirect( COUNT * 4 * 3); 
		tbb.order(ByteOrder.nativeOrder());
		_fbb = tbb.asFloatBuffer();
	    float[] src = 
			{ 	0.0f, 1.0f,0.0f,
	    		1.0f,-1.0f,0.0f,
	    	   -1.0f-1.0f,0.0f };
	    _fbb.put( src );
		_fbb.position(0);
		for( int i = 0; i < 9; ++i )
		{
			System.out.println( "Index :" + i + ", val: " + _fbb.get(i) );
		}
	}

}

It does not print what is in 'src'.

I use:
$ java -showversion
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Server VM (build 14.2-b01, mixed mode

and

$ javac -version
javac 1.6.0_21

on Linux

I came across this bug report from a while back which looks similar, but it is reported as fix-delivered.

Is this a known problem or have I got something wrong ?
Thanks

I ran your code on Java 1.6.0_20-b02 and it ran fine; b.t.w. you're missing a comma in the third line of your array initialization.

kind regards,

Thanks Jos,

that was that coma, should not have posted this :-P :-)

thanks again

You're welcome of course; indeed -1.0f-1.0f results in a single float -2.0f and your array ends up having eight elements. Add more spaces for readability ;-)

kind regards,

Jos
